Wearable device

To provide a wearable device a part of which directly comes in contact with the skin of a living body includes silicone foam and which is excellent in durability and comfortability. An earpiece 150 includes a core 152 that is attached to a sound conduit 140, and an ear canal attachment section 156 that is attached to an outer side of the core 152 and comes into contact with an ear canal inner wall of a wearer. The ear canal attachment section 156 over the entire exterior of which soft silicone foam, which is a foamed material, is disposed, can keep close contact with an ear canal and comfortable wearability, while the core 152 made from silicone rubber allows a tip portion of the sound conduit 140 to have a shape to be easily wound, which prevents a sound path from being blocked.
